IllustrativeConcrete Leveling Warranty & Service Policies
PolyJacks backs every concrete leveling job with a 1-year limited warranty: if a covered slab settles beyond the covered tolerance within twelve months, the crew returns and re-lifts it at no charge. The warranty is transferable if you sell the home. It reflects confidence in waterproof polyurethane foam, which doesn’t wash out or break down underground.
Our Concrete Leveling Warranty, in Plain Terms
When we lift a slab, we stand behind it with a 1-year limited warranty. It's transferable: sell the house, and the new owner is covered too, no extra paperwork beyond letting us know.
Here's the promise, no fine print maze: if the concrete we lifted settles more than 1/4 inch within 12 months because of our work, we come back and re-lift it at no charge.
We're a locally owned crew based in Spring Hill, and we don't disappear once the truck pulls out of your driveway. One call to (913) 713-7794 and we get you back on the schedule.
What's Covered
The warranty covers settling caused by the work we did. The foam didn't hold, or we misjudged the lift. If your slab drops more than a quarter inch under those conditions in the first year, the re-lift is free.
We measure to that quarter-inch line for a reason: concrete shifts a little with Kansas City's freeze-thaw winters and clay soil no matter what you do. A hairline movement isn't a warranty issue. A slab settling back down because our foam gave way is.
What's Not Covered and Why
We're upfront about the limits, because a warranty that promises everything protects nothing. Here's what falls outside coverage:
- Drainage or gutter neglect that keeps sending water under the slab
- Tree root growth that displaces soil after the lift
- Heavy vehicle or equipment loads on the slab within 48 hours of the job
- Acts of God: flooding, earthquakes, and the like
- Cosmetic or hairline cracks that don't affect the level of the slab
Every one of those comes down to the same idea: we can only warranty what we control. We control the lift. We don't control your gutters, a neighbor's oak tree roots, or a freak storm. If one of those is behind a slab moving again, we'll still come out, take an honest look, and give you a free estimate on fixing it right.
Why a 1-Year Term and How to Make the Fix Last Well Beyond It
A year is what we can honestly promise based on what's in our hands. The lift itself is permanent: our foam doesn't shrink, break down, or wash out once it cures. It just sits there doing its job, indefinitely.
What actually threatens a leveled slab down the road is the same thing that sank it in the first place: water finding its way underneath, poor compaction on a newer slab, or roots pushing soil around. That's true of any concrete leveling warranty, no matter who does the lifting.
The good news is most of it is preventable. Keep gutters clean and downspouts aimed away from the slab. Fix any nearby plumbing leak before or right after we lift. Foam can't hold against water actively washing soil away. If tree roots are the culprit, that needs root work, not another re-lift.
Handle those things and there's no reason a leveled slab shouldn't stay level for years past the warranty period.
Your Part: Simple Maintenance That Protects the Work
You don't need to do much, but a few habits go a long way:
- Point downspouts away from the slab, not toward it
- Keep gutters clear so water isn't overflowing near the slab edge
- Grade soil nearby so water runs away instead of pooling
- Call a plumber first if you suspect a leak near the sunken area. Foam can't out-lift an active leak
- Call us if you notice new sinking so we can catch it early
None of this is complicated. It's the same stuff that would've kept the slab from sinking in the first place, had it been caught sooner.
Filing a Warranty Claim
If a slab we lifted settles more than 1/4 inch within 12 months, call (913) 713-7794. We'll ask a few questions about what's happened around the area since (new drainage issues, tree work, anything unusual) then get the free re-lift on the schedule.
Selling the house before the year's up? The warranty transfers to the new owner automatically. Just pass along our number in case they ever need us.

Frequently asked
What exactly does the PolyJacks warranty cover?
If a slab we lifted settles more than 1/4 inch within 12 months because of our work, we come back and re-lift it for free. It's a 1-year limited warranty, and it transfers automatically to a new owner if you sell the house.
Why is the concrete leveling warranty only 1 year instead of longer?
We can only warranty what we control, and that's the lift itself. A year covers the window where a foam or installation issue would show up. Drainage, tree roots, and soil conditions affect concrete on a much longer timeline no matter who does the leveling, so those sit outside any honest leveling warranty.
What voids or excludes warranty coverage?
Drainage or gutter neglect, tree root growth, heavy vehicle or equipment loads on the slab within 48 hours of the job, acts of God, and cosmetic or hairline cracks that don't affect the slab's level. If one of those turns out to be the cause, we'll still come take a look and give you a free estimate on the next step.
Does the warranty cover cracks in the concrete?
It covers settling of the slab we lifted, not cosmetic or hairline cracking that doesn't affect how level it sits. Concrete cracks over time in Kansas City regardless of who's worked on it, thanks to our freeze-thaw winters.
What do I need to do to keep my leveled slab from sinking again?
Keep gutters clean and downspouts pointed away from the slab, grade soil nearby so water runs away instead of pooling, and handle any plumbing leaks near the area right away. Those are the same conditions that sink concrete in the first place.
How do I request a warranty re-lift?
Call (913) 713-7794. We'll ask a few questions about what's changed around the slab, then get the free re-lift scheduled if it's covered.
